MRI for identifying stroke patients most likely to benefit from tPA

This news item covering a presentation at the ARRS meeting by Gang Guo from Torontom talks about the use of MRI in identifying patients who are likely to have hemorrhagic transformation of the infarct, thus precluding them from anti-thrombolytic therapy. Apart from perfusion, it advocates the use of T1W images to identify areas of enhancement in the infarcted area and the hyperintense MCA sign.
